* MRF24J40 IEEE 802.15.4 *
Required properties:
- compatible: should be "microchip,mrf24j40", "microchip,mrf24j40ma",
or "microchip,mrf24j40mc" depends on your transceiver
board
- spi-max-frequency: maximal bus speed, should be set something under or equal
10000000
- reg: the chipselect index
- interrupts: the interrupt generated by the device.
Example:
mrf24j40ma@0 {
compatible = "microchip,mrf24j40ma";
spi-max-frequency = <8500000>;
reg = <0>;
interrupts = <19 8>;
interrupt-parent = <&gpio3>;
};
